How do you rosin your bow?

Michele

Some people stroke the rosin in one direction from frog to tip only, others start at the middle and stroke from middle out to the frog and then out to the tip. Most just stroked the full length of the bow one way and then back the other way. Another one used short strokes, 6" or so, and worked up and down the length of the hair.

Is there a preferred method of rosining a bow and, if so, does it make any difference to the quality of the sound generated?  Is there any other advantage of one method over another?
